BrainStorming:- GeoTagging Images via Google Earth?

Ive been toying with the idea of creating some kind of geotagging interface that utilises Google Earth, anyone got any ideas or suggestions as to how it could be done.

heres a few ideas ive had so far1) use the network link, once you have found the spot you want to geotag, zoom right in then refresh the network link which sends the current bounding box (BBOX) value to a server. From the BBox data, it should be possible to work out the central coordinate and then store/use it for geotagging. i guess the server would need to cross reference the users ipaddress, with the ip address that sent the BBOX data.

BTW does anyone have an algorithm for finding the central coordinate given the BBOX data?

2) use the email placemarker function, to email the location to a script that continually checks a pop mail box, in the email you could include a title and description, or comments
the script will store the location and or add it to a list of that users locations, which when they login to the server, then can use the emailed in locations like bookmarks similar to the way CK's script works at present for geotagging images

3) save the positions as placemark kml files, then once youve finished saving locations. upload the kml files to a server, which will process them and store the locations similar to the previous idea

4) this might be a bit drastic, but my other idea is to somehow add a geotagging function directly into the google earth executable file, by way of a patch of some sort, not sure how feasible this is though.
